The movement does not run as t. He crown cannot be wound. It’s likely that the mainspring needs to be replaced, at a minimum. Given this and considering that the movement has likely never been serviced a complete overhaul is required. This seldom seen vintage 1970’s Customtime complete set came from the estate of its original owner who had it tucked away unworn for the past 25 years. The black “T SWISS MADE T” signed dial is in pristine condition and the original tritium on the dial and hands, which remains fully intact and emits a faint, short-lived glow after being exposed to bright light, has aged to a perfectly matching warm buttermilk hue. The black bezel, which shows wear and very stiffly rotates bidirectionally, presents nicely. The chrome-plated case shows minor wear with no visible signs of oxidation. The outer edge of the case back is stamped “WATERRESISTANT – SWISS MADE – STAINLESS STEEL BACK – BASE METAL BEZEL” with a diver and a fish stamped in the center. The crystal shows scratching. While I normally shows pictures of the movements of watches I put up for sale the case back on this watch is torqued too tight for me to remove. The manual wind movement with quickset date function does not run and the non-screwdown crown cannot be wound, likely indicating that the mainspring needs to be replaced. The time can be set without issue and the quickset date function works flawlessly by manually rolling over a new date and then moving the hour hand repeatedly between the 21 and 24 hour marks until the desired date has been reached. Given that the movement does not run a complete overhaul is required. This watch measures approximately 36 mm excluding the crown, approximately 39 mm including the crown and approximately 18 mm between the lugs. Case thickness, measured from the bottom of the case back to the top of the bezel, is approximately 9.5 mm. Including the crystal case thickness measures approximately 11 mm. This watch comes on its original “L/34/18″ stamped rubber strap with “HONG KONG STAINLESS STEEL” stamped buckle showing little wear. While the interior of the original box shows age-related wear the exterior is well-preserved. As such there are no warranties, express or implied, attached with the sale of this watch. Vintage means old and while my personal belief is that old-school means better quality and workmanship, things can and do go wrong from time to time. For this watch that time is now. Any servicing costs going forward are your responsibility. And please study the 12 high magnification pictures carefully as they are part of the description and serve as an accurate representation of the condition of this watch.
